Resource Hacker is a small but excellent tool to modify system files like DLL, EXE, CPL, etc. You can even change Windows look by editing various Windows files and replacing their resources using Resource Hacker.
You can download it using following link:
This tutorial will help you in understanding this tool and will teach you how to use it. For your convenience, we have divided this tutorial in 2 parts:
- PART 1: BASIC INFORMATION
- PART 2: ADVANCED INFORMATION
Part 1 provides basic details like viewing or replacing existing resources in a file, etc. Part 2 covers some advance information for geeks, like adding new resources, using scripts, etc.
PART1 : BASIC INFORMATION
[Using Resource Hacker]
When you open a file in Resource Hacker, it shows various directories in left-side pane, like:
- AVI - Contains AVI files
- Cursor - Contains Cursor files
- Bitmap - Contains BMP files
- Icon - Contains Icons
- Menu - Contains Menus
- Dialog - Contains Dialog boxes
- String Table - Contains Strings
- Accelerators - Contains Shortcut keys
- Version Info - Contains Version information of the file

[Viewing Resources]
You can view resource present in the file by expanding the directory given in left-side pane and clicking on the name of the resource. Each resource contains 3 important attributes:
- Resource Type
- Resource Name
- Resource Language
[Changing Resources]
For Icons / Cursors / Bitmaps:
1. First select the resource ( e.g. Bitmap -> 131 -> 1033 ).
2. Now click on Action -> Replace Icon or Cursor or Bitmap....
![]()
3. It'll open a new window, click on Open file with new Icon or Cursor or Bitmap button.
4. Select the desired resource using OPEN dialog box, click on Open button and then click on Replace button.
For Other Resources like AVI:
1. Click on Action -> Replace Other Resource....
2. It'll open a new window, click on Open file with new resource button.
3. Select the file and click on Open button.
4. Now you'll need to provide following required information for the resource, which we mentioned earlier:
- Resource Type
- Resource Name
- Resource Language

Resource Type: Mention type of the resource, e.g. if you are replacing AVI file, mention the type as AVI
Resource Name: Provide the same name of the existing resource which you want to replace
Resource Language: Provide language code for the resource, e.g. 1033 for English. You can check existing resource's language code.
5. At last click on Replace button.
[For Menus / Strings / Dialogs]
To change any String, Menu or Dialog box, Select the desired resource, e.g. String Table -> 4 -> 1033, make your changes and at last click on Compile Script button.

It'll immediately compile the script. If you made any mistake while modifying the resource, it'll generate error message so that you can fix it.
PART2 : ADVANCED INFORMATION
[Adding New Resources]
Adding New Bitmaps / Icons / Cursors / AVIs:
1. Click on Action -> Add a new Resource....
2. Now click on Open file with new resource button.

3. Select the desired resource and click on Open button.
4. Give Resource Type, Name and Language as mentioned earlier. But keep in mind that Resource Name should not match with any existing resources name.
5. At last click on Add Resource button.
Adding New Menus:
Go to desired menu, e.g. Menu -> 215 -> 1033. Now add a new line anywhere inside POPUP "" using following format:
MENUITEM "Custom_String", 12345, MFT_STRING, MFS_GRAYED | MFS_DEFAULT
Where:
- "Custom_String" is the actual text which you want to show in menu.
- 12345 is the identifier. It must be different from existing menuitems.
- MFS_GRAYED disables the menuitem. You can change it to MFS_ENABLED if you want to show your menuitem enabled.
- MFS_DEFAULT shows your menuitem in BOLD. You can omit it.
- You can also add a new attribute in the code MFS_HILITE which automatically selects your menuitem.
In fact you can only add following new line in code:
MENUITEM "Custom_String", 12345
And Resource Hacker will automatically insert other remaining values as mentioned above.
[Inserting Newly Added Resources in Dialog Boxes]
Once you finish adding new Icons / Bitmaps / AVIs, you can insert them in any dialog box so that you can show in various Windows dialog boxes like RUN, Progress Dialog box, etc.
1. Go to the desired dialog box, e.g. Dialog -> 1020 -> 1033
2. Right-click in the dialog box and select Insert Control option.

3. It'll open a new window. You'll see many controls in the new window, like BITMAP, LABEL, ICON, BUTTON, SysAnimate32 (for AVIs), etc.
4. Click on any desired control, e.g. to insert a Bitmap, click on the BITMAP control or to insert an AVI, click on SysAnimate32 control.

PS: You can also insert Date/Time in dialog box using SysDateTimePick32 control.
5. Don't forget to fill the Caption entry. You need to enter the Resource Name in Caption textbox, e.g. if you have added a Bitmap and set its Resource Name as 401, then give the same 401 in Caption textbox.

PS: For AVI Control ( SysAnimate32 ), you'll need to append # in Caption value, e.g if the AVI name is 144, then put #144 in Caption textbox.
6. At last click on OK button & then Compile the script.
7. If you want to change the position of the new control in dialog box, simply click on the control and drag it to your desired location or you can also use arrow keys to move it.
Using Scripts in Resource Hacker
We can also run Resource Hacker using Command Prompt and can use scripts to automate lots of repeatative tasks to save our time.
You can use scripts in 2 ways:
- Single Command
- Multiple Commands
[Single Command]
You can use following commands in Command Prompt to perform actions using Resource Hacker:
-add ExeFileName, ResultingFileName, ResourceAddress, ResourceType, ResourceName,
-addskip ExeFileName, ResultingFileName, ResourceAddress, ResourceType, ResourceName,
-addoverwrite ExeFileName, ResultingFileName, ResourceAddress, ResourceType, ResourceName,
-modify ExeFileName, ResultingFileName, ResourceAddress, ResourceType, ResourceName,
-extract ExeFileName, ResourceAddress, ResourceType, ResourceName,
-delete ExeFileName, ResultingFileName, ResourceType, ResourceName,
Where:
- ExeFileName - Source file name
- ResultingFileName - Output file name
- ResourceAddress - Resource location (e.g. Bitmap path stored in your hard disk)
- ResourceType - Resource type (e.g. Bitmap, AVI, etc.)
- ResourceName - Resource name (e.g. 131, 1020, etc.)
Example:
ResHacker.exe -addoverwrite explorer.exe, explorer1.exe, MyImage.bmp , bitmap, 143,
[Multiple Commands]
You can also run a series of commands using script. First you'll need to create the script file using Notepad and then you can run it using following command:
ResHacker.exe -script ScriptFileName
Where, ScriptFileName is the name of the script file which you created in Notepad.
Following is the required format of the script file:
[FILENAMES]
Exe=
SaveAs=
Log=
[COMMANDS]
-addoverwrite ResourceAddress, ResourceType, ResourceName
Where:
EXE= contains source file name
SaveAs= contains output file name
Log= contains LOG file name which will store a detailed log of the operation
[COMMANDS] section contains the command-set which we want to perform on the source file.
PS: You can omit the LOG= entry in script file. In this case, Resource Hacker will automatically create a LOG file with the name "ResHacker.log".
NOTE: If you are facing problems while saving a file after editing in resource hacker, then make sure you have disabled WFP (Windows File Protection) service using "WFP Patcher" or use "Replacer" to replace the file.
Also if you are getting error "Can't create file...", that means you have edited and saved the same file in past and there is a backup file which needs to be deleted before saving this file again. Go to the folder containing this file and you'll see a similar file having "_original" in its name. Delete it and try to save the file in resource hacker.
That's all for now. If you have any query, please feel free to ask us...

After I replace the resources, how do I save them?
Stefan
Oh yeah, and when I apply the new resources and close the program it asks me if I want to save the changes. I save, reboot, and nothing happens.
VG
^^ Have you run WFP Patcher?
Wally
Thanks for the awesome tutorial. Spot on as usual. Just what i was looking for my project.
Robert Harrod
I found Resource Hacker through Windows 7 Forums in the tutorial "Icons - Change Using Resource Hacker". When I saw what Resource Hacker's capabilities were, I immediately downloaded it (ver 3.5.2 Beta) and followed the instructions in the above mentioned tutorial and when I got to the point of clicking on "*1033" (step 10 of the tutorial), I recieved an error message window that said "Out of system resorces." I clicked the "OK" button and everything proceeded exactly as the tutorial said that it would until the last step (reboot/restart) at which point I discovered that the file "imageres.dll" (the one I modified and saved to desktop) was unchanged. Am I doing something wrong?
Operating System - MS Windows 7 Home Premium 64-bit; Installation Date: 01 December 2010

^^ You should save the file at some other location. Then take ownership of original imageres.dll file present in System32 folder. After that rename original file to some other name like imageres_original.dll. At last copy new modified file to System32 folder and restart your system. After reboot, Windows will start using your new modified file.

Well, for whatever reason, after I let my laptop rest for the evening, everything seems to be working correctly now and I am not getting the error message window that said "Out of system resorces." anymore.
Thank-you VG for a wonderful utility that has helped me tremendously in just the few hours that I have been able to use it!

^^ You can't. Any method to do so would be considered as illegal. You can simply purchase the product to make it fully functional.
